(a) Upper panel: temperature dependence of the peak positions normalized to the peak position at as a function of the normalized temperature (). Lower panel: absolute value of normalized peak position differentiated to normalized temperature [32]. Reprinted figure with permission from Choi et al. [32].

The red arrows indicate electrons reside in the d orbitals, and the gray arrow indicates lowering of band caused by the temperature reduction.
